ALL IT MAY CONCERN:

Beit known'tliatl (LW. LUDLOW,'of Dayton,'in the county of Montgomery, and State of Ohio, have invented a new `improved Water-W'heel; and that the following.description, taken in connection with the accompanying drawings, hereinafter referred to, forms afull and exact specification of the same, wherein [have sct'forth the natureand principles of my said improvements, by which my invention may be distinguishedfromV .'rlll others of afsim'rvlnr class, together with such parts as I claim, and desire to have securedto me vby Letters vPatent.

This invention relates to a new and useful improvement in' horizontal water-wheels, and has for its object the varying (of the discharge el' the water from the wheelby varying thc capacity of the issues, and also 'by regulating the action or suction of the draught-wheel, whereby the capacity of thewhcel may be regulated to snit the amount of power it is required to give out, and the wheel madeto work at a less power than its makimum, with` the use o'fanroportionate amount of waterlonly. In the accompanying sheet of drawings- I Figure 1 is a vertical section of my invention, taken in the line a; x, fig. 2.

A A represent two rims or annular plates, placed one above the other, and having chutes B placed between them to guide or direct thc water properly against the buckets of the wheel.- C represents a conc, attached to the upper rim A to serve as a-cover, and D 'represents the wheel, composed of a solid circular top pla-te, E, and' a bottom rim, F, connected by vertical bolts or uprightsaX, the buckets G of the wheel being between E and l? and fitted on central pivots or rods The buckets G are slightly curved in serpentine form, as shown clearly in iig. 2, and their pivots or rods a extend up through the top plate Eef the wheel, and have arms b attached to them, one to each, as shown clearly in tig. 2. The outer ends of the arms b are connected by rods c to the lower end of a collar,-H, which is placedjloosely on the shaft I, and allowed to slide freely up and down thereon. This collar Il hasA a yoke, J, fitted upon it, and this yoke 'has two rods, K K, attached to it, which pass up through the upper part of the c'pne1 and are v.attached to'a lever, L, the fulcrum d of which is in the upper end of an upright, M, on the conc.

From the above description it will be seen that by adjusting the lever L the collar H will be raised and lowered on the wheel-shaft Land the buckets G turned or adjusted so that the. issues al betweenwthe buckets may be Venlarged or diminished as required. i

The lower end of the wheel-shaft I is 'stepped ina bridge-treqN, the ends of which are attached to the.'

lower rim A. The wheel, in practice, is placed halfway between the head and tail water, and a, suction or draught-tube, O,.is attached to the lower rim A. Hence, with twenty feet head and fall, there will `he ten feet of headabove thc wheel and ten feet of suction of draught-tube below. To the suction or draught-tube is attached a ventilatingpipe, P, which extends up above the` surface of the water. This pipe P has va valve, Q, inserted in it', which is turned or operated by a governor or otherwise, .so as to give more or less 'venit to the tube P and control thesuction or draught in tube O, as may be desired.

By these two means-towit, the regulating of the capacity of the issues between the buckets, and the regulating ofthe suction or draught within the tube O-the wheel may be run at a less power than its maximum, and with an expenditure of water commensurate with the power given out by the wheel.

The great objection to horizontal water-wheels lhitherto has been the loss of water whenever a wheel is run 1t less `than itsniaximum power, more water .being consumed in proportion than when the wheel is run at its maximum. This diiiculty is believed to be fully `obviated by my invention.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The construction and arrangement of the arms b, attached to the pivoted rods a of the buckets G, their inner ends connected by the rods "C to the sliding collar H, operated by means of the rods K and lever L, as herein set forth, for the purpose speciiied. f

2. The vent-tube or Ventilating pipe P, applied tothe draught-tube 0 and, provided with a. valve, substan.
